FWIW, I do *not* suggest using the SystemOutLogger/DefaultDelegateFactory if you require decent performance - it's completely synchronous and will slow things down substantially.

I'd suggest SLF4J + a well-configured JBoss Logging setup.

Great, I will check that.

The default logger seems to work fine for me, e.g.

apiman-gateway.logger-factory=io.apiman.common.logging.DefaultDelegateFactory

Double check you didn't accidentally null the entry out by overwriting it later in your config.

For SLF4J, the WAR implementation doesn't have the logger on the classpath by default. You can do it manually, but it's a bit of a hassle and is only a small addition, so I've added it and it will be in the next release:

Hi,

I have managed to build these 2 projects (apiman-common-logging-core and /apiman-common-logging-slf4j) and add it as global jboss module to make Apiman to use Slf4jLoggerFactory logger.

Does it not work out of box with just specifying Slf4jLoggerFactory in apiman.properties?

I'll try to look into it shortly and post back onto the ML.

Hi Marc,
thanks for your quick response. Unfortunately it doesn't work.

Although, what I am trying to achieve is to use "Slf4jLoggerFactory" and it fails with same null pointer.

I think you want 
io.apiman.common.logging.DefaultDelegateFactory in that field rather than SystemOutLogger directly.

Does that work?

The name is probably confusing - it *was* the default one at some point.

Hello,

I'm trying to simply replace the NoOpLoggerFactory to SystemOutLogger in apiman.properties and get below exception. It is quite strange as SystemOutLogger  is infact implements IDelegateFactory.

#apiman-gateway.logger-factory=io.apiman.common.logging.impl.NoOpLoggerFactory
apiman-gateway.logger-factory=io.apiman.common.logging.impl.SystemOutLogger 

Also, If I try to change to Slf4jLoggerFactory, then even the Slf4jLoggerFactory.class is not found.

Could you please advise if there is any reference to be added and causes below error. Thanks
